RE: HTTP/1.1 502 Proxy Error - Resolution

[Jon S <rvrratjon@xxxxxxxxxxx>]

   I have this figured out and thought I'd post the resolution in case
   anyone else came across this. Per my vendor:

   RFC 2616:

           Many older HTTP/1.0 and HTTP/1.1 applications do not
   understand the

   Expect header.


   So, I commented out the


   eval wwReqChain = wwReqChain +
   'Expect: 100-continue' + CRLF


   from the do_post procedure in HTTPAPIR4 and updeted the service
   program and all is well. I am going to look into making that
   conditional somehow.

   It turns out that they are running an older proxy in production then
   they are in their test area so that is why it started failing.

   Thanks, Jon
